🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winEnsure the Vector state HostPath is writable by UID 1000.
GetDataPath(...)is mounted read-write, andrun-vector.shcreates that directory for persistent state. The pod now runs as UID 1000 withFSGroup: 0.FSGroupdoes not change ownership or mode on aHostPath. If the existing directory tree is not writable by UID 1000 or group 0, Vector cannot persist checkpoints or on-disk buffers after an upgrade. Ensure the relevant HostPath directories and parent directories are writable before rollout.🤖 Prompt for AI Agents

Provision the Vector data HostPath with write access before starting the collector.
CollectorVisitor mounts GetDataPath(...) as a writable HostPath for both DaemonSet and Deployment collectors. The volume has no creation or ownership configuration, and no repository code provisions or changes its ownership.
The collector runs as UID 1000 and drops FOWNER, CHOWN, and DAC_OVERRIDE. On a node where the existing HostPath directory is root-owned, chmod 770 returns EPERM. run-vector.sh does not stop on that failure, so Vector starts without a writable data_dir. Vector uses this path for its state and disk buffers, which can disrupt collection when a disk buffer is required.
Provision each data directory with UID 1000 ownership or write access for GID 0 before scheduling the collector. The non-root startup script cannot establish ownership on an existing HostPath.
